Abstract: A process for the preparation of stable, non-aqueous dispersions of water-soluble, preferably high-molecular-weight, polymers which have been prepared by polymerisation of at least one water-soluble  alpha , beta -ethylenically unsaturated monomer in a W/O emulsion and from which the water has been removed azeotropically to a residual water content of less than 5% by weight, based on the polymer, by irradiation with microwaves. The dispersions preferably have polymer concentrations of between 20 and 65% by weight. The azeotropic removal of water is carried out according to the invention by irradiation with microwaves having a wavelength of, preferably, 0.1 to 30 cm.

Abstract: Eine Farbdosiereinrichtung zum Erzeugen eines Farbprofils auf der Farbkastenwalze einer Druckmaschine ist mit einzeln verstellbaren Farbschiebern (1) ausgerüstet. Zur Justierung der Farbschieber gegenüber der Farbkastenwalze (3) ist in den Antrieben zum Verstellen der Farbschieber jeweils eine Rutschkupplung (6) vorgesehen. Der maximale Verstellweg der Farbschieber soll größer sein als der durch die Einbaumaße mögliche Hub. Zum Justieren der Farbschieber an der Farbkastenwalze werden diese bis zur maximal möglichen Verstellung angestellt, wobei die Rutschkupplung die Differenz des Verstellwegs ausgleicht und die nun justierte Stellung an einem Potentiometer abprüfbar ist.

Abstract: In front loaders designed for drive-in attachment to tractors, a detachable main portion of the loader has been supported, when not in use, at its front end by its bucket and at its rear end by two struts pivotable between stowed and deployed positions. Also, loaders in general have usually been provided with struts for temporarily locking in its fully raised position the boom assembly which is pivotable by hydraulic cylinders and carries the bucket. Economy of design is achieved by employing two telescopic struts (58) pivotable between a stowed retracted position alongside the boom assembly (21); a first deployed extended position for supporting the rear end of the detachable main portion, aided by auxiliary struts (35), when it is not attached to the tractor; and a second deployed extended position, alongside the hydraulic cylinders (27) which pivot the boom assembly (21), for locking the boom assembly (21) in its fully raised position whilst the detachable main portion is attached to the tractor.

Abstract: An annular valve seat is fitted in a rotary fluid control valve of the butterfly type. The seat consists of a radially outer tail portion (22), a radially intermediate metal support portion (30) in the shape of an S and a radially inner metal seal portion (40) having a metal sealing surface (44) in the form of an annular semi-torus. The seal portion includes structure for retaining an elastomeric sealing insert (50). The valve seat is inserted in a groove between the valve body (11) and an insert (16), with a small space existing between the axial sides of the groove and the axial sides of the S-shaped intermediate portion (30). The intermediate portion (30) accordingly permits limited flexure in response to pressure stresses on the valve seat, but the flexure is limited by contact with the walls of the groove. The metal and elastomeric sealing surfaces provide leak-free sealing with an extending life.

Abstract: A MOS type semiconductor device is manufactured by forming a field oxide film (22) on a semiconductor substrate, forming a polycrystalline silicon gate electrode (25) on an active region of a semiconductor silicon substrate, forming diffused regions (26, 27) in the substrate, the diffused regions being of a conductivity type opposite to that of the substrate, forming an oxide film (32) on the polycrystalline silicon gate electrode, depositing over the entire surface a doped polycrystalline silicon film (34) and a silicon nitride film (35) such that the surface of the nitride film abovethe diffused regions is lower than the surface of the field oxide film (22), depositing a resin film (36) to planarise the entire surface, uniformly etching the various films until the surface of the field oxide film (22) is exposed, partially etching away the field oxide (22), forming channel stop layers (42,43) and etching to expose the polycrystalline silicon film (34) which is thus divided into two parts (44, 45) which are used as electrodes for the diffused regions (26, 27). In the resulting semiconductor device, the junction capacitance between the diffused layers and the channel stops can be reduced and formation of bird's beak under the field oxide film can be prevented so that it is possible not only to miniaturise the active region but also to avoid the narrow channel effect.

Abstract: The rollers or curved rods and other elements supporting the glass sheets as well as the apparatus necessary for bending and/or tempering are preferably mounted on a pair of longitudinally flexible strips that rest on a pair of rigid templates having the desired curvature. Each flexible strip advantageously is a chain whose links are hinged on one another, these links being provided with flanges to which are fastened the rollers or curved rods, all other elements for supporting the glass sheets, and the elements necessary for bending and tempering. To permit modification of the curved profile, the templates are removable and interchangeable. To facilitate changing of the templates, the apparatus is equipped with a system for lifting the strips or chains. Such lifting system comprises one or more pivoting beams that are lifted by drive means such as a jack and a bent connecting rod. When the beams are raised, they lift the strip or chain off the template, thereby freeing the template to be replaced with a template having a different curvature.

Abstract: Synchronisation signals are transmitted in the form of alternating digital words placed at the beginning of the lines of a television signal. Receiving apparatus comprises means (20, 21) for deriving a signal indicative of the presence of each of the digital words and an evaluating circuit (22, 25) which compares the derived signal representing each word with the same signal derived one line earlier and stored in a delay circuit (24) in order to determine whether the correct alternating sequence has been received and to generate a line sync signal if the correct sequence has been received. In a further embodiment adaptive control of the evaluating circuit (23, 25) is provided. Field syncs can also be generated by detecting repetition of one of the words at the end of one field and repetition of the other of the words at the start of the next field.
